choosing between X-T1 and Sony A7

I have the Sony RX1 for FF and will add the X-T1 with the 14mm 2.8, 56mm 1.2 and a zoom. For me this seems the best of both worlds and either camera gets the job done. FF and APS-C have their own characteristics and it is clever to use them simultaneously with two seperate bodys. Thats my conclusion of the dilema.

I heard rumors that metabone might develop a Canon EF speedboster adapter for Fuji x-mount. This way we could use all Canon FF lenses with there native focal lenght on the Fuji APS-C. I hope AF-speed and IQ can hold up with such a speedbooster.

Agree with you , nothing like owning a Full frame and an APSC , solves alll your problem,

if you can afford it...:-) , most enthusiasts are pulling all stops just to own one of these beauties...

about speedboosters , I am not such a big fan , for the following reasons

1) you have to buy a full frame lens , which is heavy and expensive

2) you might not get the exact focal length you need, example APSC ( with boosters) + 55 mm carl zeiss, will give you 40 mm .. which is kind of an odd focal length
